Electronic display mounting system

ABSTRACT

An electronic sign having slotted frame cabinets whereby each slotted frame cabinet can conveniently be attached to one or more vertically or horizontally positioned adjacent slotted frame cabinets by using connecting components which are generally located around the periphery of one or more slotted frame cabinets. Connecting components, including splice bars, splice plates, and mounting clamps, are aligned in, positioned along and secured to backing bars which are co-located in backing bar slots in one or more of the slotted frame cabinets. Lift eyes can be variably located in one or more lift eye slots. The use of externally located connecting components, which do not extend through the cabinetry, minimize the entry of environmental elements into the interior of the electronic sign. Multiple slotted frame cabinets can be connected without the removal of LED display panels.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention is for an electronic sign, and more particularly,for an electronic sign having slotted frame cabinets wherein eachslotted frame cabinet conveniently attaches to one or more vertically orhorizontally situated adjacent slotted frame cabinets. An individualslotted frame cabinet can also be utilized by itself for use as anelectronic sign.

2. Description of the Prior Art

The invention is to be used as a replacement for current technology signstructures which are very labor intensive and which require welding,individual component fitting, drilling, and the like. Welding is verytime consuming and is a hard process to control with respect touniformity and trueness of surfaces. Welding also reduces the strengthcharacteristics of aluminum structures used therein and thereabout. Thenew invention uses structural rivets for cabinet component attachment,thus eliminating the need for welding. Joining of components such as,but not limited to, formed channels to the slotted frames of the slottedframe cabinet is accomplished by the use of prepunched and preformedcomponents and rivets. The use of structural prepunched and preformedcomponents with rivets allows for the automation of the entire processof fabrication. The prepunched holes used for the accommodation ofrivets self-align the component parts, thus substantially reducingmanufacturing labor.

The new invention eliminates the need for nutserts and other traditionalfastening schemes used for splicing and joining adjacent slotted framecabinets and eliminates the need for attaching clip angle supports tothe rear of an electronic sign cabinet. It does this by havingsubstantially continuous slotted frame cabinets which can acceptexternal splicing and connection structures such as mounting clamps,splice plates, backing bars, and the like, which can convenientlysplice, align and secure adjacent slotted frame cabinets together invertical or horizontal relationships.

Prior art devices relied on installing nutserts for splicing andattaching clip angles to the rear of a cabinet for mounting and/orinstallation purposes, each of which requires extra assembly steps and,when installed, do not have variable placement. The use of continuoushorizontally aligned backing bar slots eliminates the requirement forthe use of horizontal stringers on the rear of a sign structure whichwere used for mounting to various support structures.

Many prior art devices fail to accommodate unequally spaced verticallyaligned ground mounted support structure. The invention provides asolution for such variable positioning of ground mounted supportstructure by providing slot mounted positionable mounting clamps alignedat variable spacings in slots along the entire horizontal length of oneor more joined slotted frame cabinets to accommodate variably spacedground based support structures such as, but not limited to, verticallyaligned I-beam supports.

Prior art designs have been such that lift eyes penetrate the cabinetinterior and are placed at predetermined points in the cabinet frame.The disadvantage of such a system is that it is labor intensive toattach the lift eyes. Furthermore, such through the cabinet structuremounting allows entry points for the elements. This present inventionallows for flexibility in the lift eye location by allowing the lift eyeto translate anywhere along a lift eye slot in the length of one or moreof the cabinet sections. The lift structure does not communicate withthe interior of the cabinet sections.

This invention also provides for a watertight assembly because thecabinet interior is not penetrated by the use of fasteners, such as usedin prior art devices. The slotted frame cabinet interior is notpenetrated during factory or on-site installation since cabinet sectionsare spliced externally by components which align to or within externallylocated slots located along and about the cabinet frame.

Prior art devices in the field required the removal of electronicdisplay modules in order to splice cabinet sections, as splicing of onecabinet section to another required internal access to mountinghardware, connector plates, and the like. The present invention allowsexternal connective splicing of vertically or horizontally adjacentcabinet sections without accessing the interior of a slotted framecabinet.

SUMMARY OF THE INVENTION

The general purpose of the present invention is to provide an electronicsign having slotted frame cabinets. According to one or more embodimentsof the present invention, there is provided an electronic sign comprisedpartly of slotted frame cabinets where the use of two or more slottedframe cabinets provides for a full complement of connective components,such as described herein. In the alternative, an individual slottedframe cabinet can be utilized to provide for a unitary electronic sign.Slotted frame cabinets which are central to the invention areconstructed and joined together by using a plurality of similar profilegeometrically configured components including a frame top, a framebottom and frame ends, each of which has a plurality of externalaccessible slots extending along the length thereof. A plurality offormed vertically aligned channels and formed mid-channels are securedbetween the frame top and the frame bottom of each slotted frame cabinetwhich serve, in part, as a mounting structure for a front mounted panel,the latter of which accommodates a plurality of electronic displaymodules. The preformed vertically aligned channels also serve, in part,as a mounting structure for rear panels. A shroud surrounds theperimeter of the joined slotted frame cabinets.

The slotted frame cabinets are joined by unique components and methods.Horizontally adjacent and aligned slotted frame cabinets are joined bythe use of one or more geometrically configured splice bars in verticalorientation which align in and between opposed like slots in the frameends of adjacent horizontally slotted frame cabinets and, in cooperationtherewith, are also joined by splice plates secured to opposedvertically aligned backing bars in opposed like backing bar slots in theframe ends of the adjacent slotted frame cabinets. Installation of thesplice plates provides for self-alignment of the frame ends ofhorizontally adjacent slotted frame cabinets.

Vertically adjacent and aligned slotted frame cabinets are joined by theuse of one or more geometrically configured splice bars in a horizontalorientation which is or are aligned in and between opposed like slots inthe frame top and frame bottom of vertically adjacent slotted framecabinets and, in cooperation therewith, are also joined by mountingclamps serving, in part, like splice plates secured to opposedhorizontally aligned backing bars. Installation of the mounting clampsprovides for self-alignment of the frame tops and bottoms of verticallyadjacent slotted frame cabinets. The mounting clamps are also used tosecure joined combinations of slotted frame cabinets; i.e., theelectronic sign having slotted frame cabinets, to ground mounted supportstructure. The mounting clamps are horizontally positionable along thesign in order to connect to unequally spaced support structure. A lifteye slot is also included along the frame top to slidingly accommodateone or more lift eyes.

One significant aspect and feature of the electronic sign having slottedframe cabinets of the present invention is the use of multiple slotsalong and about the perimeter to which a plurality of connection devicesor other devices can be attached, captured and secured.

Still another significant aspect and feature of the present invention isthe use of common geometry slotted frame components including a slottedframe top, a slotted frame bottom, and slotted frame ends which formconnected inner panels where the slotted frame top and the slotted framebottom serve as mounts for vertically aligned formed channels includingformed mid-channels. The perimeter of the slotted frame components andthe formed vertically aligned channels are not welded but are riveted inprepunched holes in order to automate the fabrication process and toimprove reliability, manufacturability, tolerances, repeatability, andefficiency of assembly.

Another significant aspect and feature of the present invention is theuse of adjacent perimeter splice bar slots in common with an intercedinggeometrically configured splice bar to align within and therebetweensuch slots to, in part, mutually secure the forward region ofhorizontally adjacent and aligned slotted frames ends or the forwardregion of vertically adjacent and aligned slotted frame tops andbottoms.

Another significant aspect and feature of the present invention is theuse of backing bars residing in backing bar slots and used with spliceplates to, in part, join the rearward portion of horizontally adjacentand aligned slotted frame cabinets.

Another significant aspect and feature of the present invention is theuse of splice plates to align the fronts, rears and splice bar slots ofthe horizontally adjacent slotted frame cabinets.

Another significant aspect and feature of the present invention is theuse of backing bars residing in backing bar slots and used with mountingclamps to join the rearward portion of vertically adjacent and alignedslotted frame cabinets.

Another significant aspect and feature of the present invention is theuse of mounting clamps to align the fronts, rears and splice bar slotsof the vertically adjacent slotted frame cabinets.

Another significant aspect and feature of the present invention is theuse of backing bar mounting clamps and associated backing bar(s), thelatter of which are horizontally positionable along backing bar slotsalong the horizontal length in order to align with variably spacedvertically aligned support structures, such as, but not limited to,I-beams.

Another significant aspect and feature of the present invention is thatthe lift eyes can be situated at an appropriate location in one or morelift eye slots along the length of the slotted frame top of one or morehorizontally adjacent slotted frame cabinets to evenly distribute theweight during installation and during display.

Another significant aspect and feature of the present invention is thatany connection points, splice plates, splice bars, mounting clamps, lifteyes, and the like are external to the slotted frame cabinet structureand, as such, there is no structural penetration by water and otherunwanted fluid or debris.

Another significant aspect and feature of the present invention is theability to join vertically or horizontally adjacent slotted framecabinets without the removal of display modules.

Having thus briefly described one or more embodiments of the presentinvention and having mentioned some significant aspects and features ofthe present invention, it is the principal object of the presentinvention to provide an electronic sign having slotted frame cabinets.

The front surfaces of the formed channels 20 andthe formed mid-channels 22 serve as a mount for the mounting panel 18and the rear surfaces of the formed channels 20 serve as a mount for aplurality of rear vent panels 24 a-24 n, as also shown in FIG. 2.

FIG. 2 is an isometric rear view of the electronic sign having slottedframe cabinets 10 of FIG. 1; and FIG. 3 is an exploded rear view of theinvention components of FIG. 2. With reference to FIGS. 1, 2 and 3, thepresent invention is further described. Similarly constructed slottedframe cabinets 26 are central to the invention and can be designated asa plurality of slotted frame cabinets 26 a-26 n or, alternatively, as aslotted frame cabinet 26 as the construction is the same. The slottedframe cabinets 26 a-26 n can be arranged as shown in FIG. 3 and areconnected by other components of the invention. One such connectingcomponent is in the form of similarly shaped geometrically configuredsplice bars 28 a, 28 b and 28 c, each having an elongated Y-shapedprofile including similarly numbered features as shown in FIG. 4. Splicebars 28 a and 28 b are shown in vertical orientation and can be used, inpart, to connect the adjacent frame ends of horizontally adjacentslotted frame cabinets 26 a and 26 b and, of course, the adjacent frameends of horizontally adjacent slotted frame cabinets 26 c and 26 n,respectively, as later described in detail. Splice bar 28 c, shown inhorizontal orientation, can by itself, or if divided in halves, be used,in part, to connect the slotted frame bottom of cabinet 26 a to theslotted frame top of the vertically adjacent cabinet 26 c and, in part,to connect the slotted frame bottom of cabinet 26 b to the slotted frametop of the vertically adjacent cabinet 26 n, respectively, as laterdescribed in detail.

Other connection components are in the form of a plurality of spliceplates 30 a-30 n in cooperation with a plurality of vertically orientedbacking bars 32 a-32 n which, in part, are used to connect the adjacentframe ends of horizontally adjacent slotted frame cabinets 26 a and 26 band, of course, the adjacent frame ends of horizontally adjacent slottedframe cabinets 26 c and 26 n. Other connection components are in theform of the plurality of mounting clamps 14 a-14 n used in cooperationwith a plurality of horizontally oriented backing bars 34 a-34 n. Someof the mounting clamps 14 a-14 n and backing bars 34 a-34 n are used, inpart, to connect vertically adjacent frame bottoms and frame tops ofvertically adjacent slotted frame cabinet pair 26 a-26 c and pair 26b-26 n. Some of the mounting clamps 14 a-14 n and backing bars 34 a-34 nare used to connect the frame tops of the slotted frame cabinets 26 aand 26 b to some of the support structures 12 a-12 n and some of themounting clamps 14 a-14 n and backing bars 32 a-32 n are used to connectframe bottoms of the slotted frame cabinets 26 c and 26 n to some of thesupport structures 12 a-12 n. All of the mounting clamps 14 a-14 n andassociated backing bars 34 a-34 n are used to connect the slotted framecabinets 26 a-26 n to all of the support structures 12 a-12 n,respectively.

A multiple component shroud 36 surrounds the perimeter of the joinedslotted frame cabinets 26 a-26 n. The shroud 36 is comprised of aplurality of elongated L-shaped shroud panels 38 a-38 n secured aboutthe perimeter of the slotted frame cabinets 26 a-26 n and a plurality ofshroud corners 40 a-40 n secured to some of the ends of the shroudpanels 38 a-38 n. A plurality of positionable lift eyes 42 a-42 n arelocated along the top of the slotted frame cabinets 26 a-26 b, asdescribed later in detail.

Each of the slotted frame cabinets 26 a-26 n uses a plurality of likestructure slotted top, bottom and end components in the form ofconfigured box tubes to form such slotted frame cabinets. FIG. 4 is across section view of a horizontally oriented slotted frame top 44 aalong line 4-4 of FIG. 5. A variety of panels and slots comprises thedescribed cross section shown in FIG. 4. An inner panel 46 opposes anouter panel 48 which panels are mutually connected by a front panel 50,a mid-panel 52, and a back panel 54. The outer panel 48 includes anoutwardly located splice bar slot 56 and an adjacent inwardly locatedlift eye slot 58. The splice bar slot 56 includes angled slot walls 56 aand 56 b. A forwardly located front mounting panel 60 extendsperpendicularly from one end of the outer panel 48 and inwardly towardthe center of the slotted frame cabinet 26. A rear mounting panel 62extends perpendicularly from one end of the inner panel 46 and inwardlytoward the center of the slotted frame cabinet 26. A rearwardly locatedbacking bar slot 64 is located between the rear portions of the outerpanel 48 and the inner panel 46. The cross section of a verticallyoriented slotted frame end 44 b, the cross section of a verticallyoriented slotted frame end 44 c, and the cross section of a verticallyoriented slotted frame bottom 44 d are substantially the same where eachhas a different orientation. All or some of the features described canbe utilized for accommodating closely associated components, asdescribed later in detail.

FIG. 4 also shows an end view of components which can be accommodateddirectly by the slots of the slotted frame top 44 a. The sameaccommodating relationships also exist with the slotted frame end 44 b,the slotted frame end 44 c, and the slotted frame bottom 44 c, asapplicable. The splice bar 28 c, which is shown in a horizontalorientation, has a plurality of panels extending at angles from acentral panel 66, including opposed panels 68 and 70 extending from thecentral panel 66, and another panel 72 offset from the central panel 66by a short panel 74. The opposed panels 68 and 70 of the splice bar 28 care aligned with and are mutually secured within the angled slot walls56 b and 56 a, respectively, of the splice bar slot 56. Interaction ofthe splice bar 28 c and other splice bars with splice bar slots 56 isdescribed later in detail. Splice bars 28 a and 28 b have the sameprofile but are used in vertical orientation. An end view of the lifteyes 42 a-42 n, each having a horizontally orientated base panel 76, aconnected vertically oriented panel 78, and a hole 80 extending throughthe panel 78, is also shown. The base panels 76 of each of the lift eyes42 a-42 n are slidingly accommodated by the lift eye slot(s) 58 of the20 slotted frame tops 44 a. Threaded holes 82, one of which is shown,are included at opposing ends of the base panel 76 for the use of bolts(not shown) which can extend therethrough to contact the bottom of thelift eye slot 58 to provide a frictional engagement arrangement of thelift eyes 42 a-42 n in the lift eye slot 58. The backing bar 34 a in theform of a channel is also shown which includes holes 84 extendingtherethrough. Backing bars 34 a-34 n are slidingly accommodated bybacking bar slots 64 in each of the slotted frame tops 44 a and slottedframe bottoms 44 d. Backing bars 32 a-32 n, having the same crosssection and shape as backing bars 34 a-34 n, are slidingly accommodatedin some of the backing bars slots 64 of the slotted frame ends 44 b and44 c.

FIG. 5 is an isometric view of a single slotted frame cabinet 26 andsome associated components which view represents anyone of the slottedframe cabinets 26 a-26 n. The ends of each of the slotted frame top 44a, the slotted frame ends 44 b and 44 c, and the slotted frame bottom 44d are miter cut and are suitably joined by right angle brackets 86 a-86n connecting the inner panels 46. The inner panel 46 of the slottedframe top 44 a and the opposed inner panel 46 of the slotted framebottom 44 d serve as mounts for the opposing ends of the preformedvertically oriented formed channels 20 and formed mid-channels 22, asdescribed with reference to patent application Ser. No. 11/809,107 filedon May 31, 2007, entitled “Electronic Sign Having a Formed MetalCabinet.”

Preferably, the general relationship and uses of several previouslydescribed components to a slotted frame cabinet 26, but not necessarilyto any of the specific slotted frame cabinets 26 a-26 n, is demonstratedwith certain exceptions below. For example:

1. As previously described, the lift eyes 42 a-42 n can align in thelift eye slots 58 when the slotted frame cabinet 26 is used as theslotted top frame cabinet 26 a or 26 b.

2. The splice bar slot 56 in the slotted frame top 44 a and the splicebar slot 56 in the slotted frame bottom 44 d can accommodate a splicebar 28 c. However, the preferred mode of assembly is the use of a splicebar 28 c to join the slotted frame top 44 a of the lower slotted framecabinets, such as horizontally adjacent slotted frame cabinets 26 c and26 n, to the slotted frame bottoms 44 d of the upper slotted framecabinets, such as horizontally adjacent slotted frame cabinets 26 a and26 b.

3. The splice bar slot 56 in the slotted frame end 44 b and the splicebar slot 56 in the slotted frame end 44 c can accommodate splice bars 28a or 28 b. However, the preferred mode of assembly is the use splicebars 28 a and 28 b to join the slotted frame end 44 c of the slottedframe cabinets, such as vertically adjacent slotted frame cabinets 26 aand 26 c to the slotted frame ends 44 b of the slotted frame cabinets,such as vertically adjacent slotted frame cabinets 26 b and 26 n.

4. The backing bar slots 64 in the slotted frame top 44 a and thebacking bar slots 64 in the slotted frame bottom 44 d can accommodatebacking bars 34 a-34 n.

5. The backing bar slots 64 in the slotted frame ends 44 b and 44 c canaccommodate backing bars 32 a-32 n.

6. The splice plates 30 a-30 n utilize pairs of backing bars 32 a-32 nfor attachment to some of the backing bar slots 64, as described laterin detail.

7. Individual mounting clamps 14 a-14 n utilize one or more backing bars34 a-34 n for attachment to some of the backing bar slots 64, asdescribed later in detail.

Support brackets 87 which can be secured at appropriate locations alongthe support structures 12 a-12 n are also shown. The support brackets 87can be used as a support during installation of the electronic signhaving slotted frame cabinets on the support structures 12 a-12 n toprovide either temporary or permanent support.
